• * Fix excessive call to subcommand's final_callback
    
    When parse_complete_callback_ is set there is an extra call to
    run_callback() inside the App::_parse(std::vector<std::string>&) method.
    This extra call also excessively calls a final_callback_ (when it is
    also set) for the command and (since it is recursive) for it's
    subcommands.
    
    This commit adds extra boolean parameter for the run_callback() method
    allowing to explicitly suppress calling to final_callback_. The value of
    this parameter is also propagated to recursive calls to run_callback().
    
    Fixes #572
    
    * fix: main app should run final_callback, add tests
